Answer:
The correct answer is -Sponges lack true tissue but have morevariation in cell type than animas in oter phylum.
Explanation:
Sponges are belong under phylum porifera which have diverse form encrusting sheets to volcano shaped mounds.
The tubes that contain in their body are differ in size from millimeter upto one meter.
The poriferans contain canal system and with help of this, they pump water which enters through a specialed pores called ostia that flows through canal called spongocoel and finally the water exits from their body through oscula.
The sponges show complex organization as their body contain single tube with 2 cell layer thick.
Ascon,leucon,sycons are the level of complexity.
Goiters are often produced in the Thyroid. Goiters is an enlarged thyroid gland. Goiters are believed to be painless, but Goiters make it difficult for the victim to breathe and swallow food. Goiters are caused by lack of iodine in one's diet. Treatment of Goiters depends on its size, some Goiters go away without any treatment while some goiters are treated through surgery.
Energy travels through a food chain/web. When an organism eats another organism, the energy from the food is passed to the eater. For example, we humans eat food to give ourselves enough calories (energy) to function properly.
<h2>Vasa recta </h2>
Explanation:
The vasa recta is a specialized capillary that branches from the efferent arteriole; The blood flow in the vasa recta runs parallel, but in the opposite direction to the flow of tubular filtrate within the nephron loop
- The vasa recta capillaries are long, hairpin-shaped blood vessels that run parallel to the loops of Henle
- The hairpin turns slow the rate of blood flow, which helps maintain the osmotic gradient required for water reabsorption
- Absorbed water is returned to the circulatory system via the vasa recta, which surrounds the tips of the loops of Henle
- Because the blood flow through these capillaries is very slow, any solutes that are reabsorbed into the bloodstream have time to diffuse back into the interstitial fluid, which maintains the solute concentration gradient in the medulla; this passive process is known as counter-current exchange
Answer:
"Take over" the area and become more successful than the native species
Explanation:
Invasive species are species that are introduced to a habitat they are not native to. They are environmentally problematic becasue they disrupt native ecosystems in which they are able to thrive. They do not usually breed with existing species, they can disrupt existing food chains, and they wouldn't be invasive if they died out.
